Title: Apparatus and method using compressed codes for scheduling broadcast information recording
Inventor: YUEN HENRY C
IPC: H04N5/76
Filed: 1992-12-11
Abstract: Digital compressed codes, asso-ciated with advertisements enable a user to selectively record additional informa-tion, which would be broadcast on a television channel at a later time. The advertisement could be print advertise-ment or broadcast advertisement on tele-vision or radio. The user enters the digi-tal code (I code) (652) associated with an advertisement into a unit with a de-coding means (14) which automatically converts the code into CTL (Channel, time and length). The unit within a twen-ty-four-hour-period activates a VCR  (14) to record information on the televi-sion channel (18) at the right time for the proper length of time. The decoded channel, time and length information can be communicated directly to a VCR  (14), and used by the VCR (14) directly to automatically activate the VCR (14) to record a given television information broadcast corresponding to the communicated channel, time and length. Alternately, the channel, time and length information can be decoded directly in a remote control unit (80) and only start record, stop record and channel selection commands (16) sent to the VCR (14) at the appropriate times.  Algorithms for decoding the I codes (652) can be a function of time to ensure security of the decoding method. A method is included for use of the I codes (652) with cable chan-nels.

Patent CA-2125950-A1 (CA)
Title: Retail coupon document
Inventor: TUCKER LARRY H
IPC: A63F3/06
Filed: 1992-03-13
Abstract: A retail coupon document (D) contains two coupons (A', B') which are hidden from a coupon user, the coupons (A', B') being for different values. The user selects and pulls one of two intersecting pull strips (20, 22), thereby revealing one of the coupons and destroying the other, depending upon which pull strip is selected.  The pull strips (20, 22) are formed by perforated division lines (24, 26, 34, 36) which are so arranged that a downstream portion (60, 64) of each pull strip (20, 22) passes through one of the coupons (A', B'). Thus, the revealed (non-destroyed) coupon will possess such downstream perforations. The perforated lines (24, 26, 34, 36) are configured such that each pull strip is less resistant to being pulled off in an upstream portion thereof (58, 62) than in a downstream portion thereof (60, 64). This ensures that the revealed coupon will not be unduely weakened by the presence of perforations therein.
